Re: [Xen-users] Assign IP's

["Stefano Cislaghi" <s.cislaghi@xxxxxxxxx>]

Also me I'm experiencing in a similar problem. I want that my virtual
machine get a static IP from outside. This is my cfg file:

xen:~# vi /etc/xen/vx1.cfg

kernel = '/boot/vmlinuz-2.6.16-2-xen-686'
ramdisk = '/boot/initrd.img-2.6.16-2-xen-686'
memory = 256
name   = 'vx1'
root   = '/dev/sda1 ro'
disk   = [ 'file:/vx/domains/vx1/disk.img,sda1,w',
'file:/vx/domains/vx1/swap.img,sda2,w' ]

# network
vif=[ '' ]
dhcp="off"
ip="151.39.235.217"
netmask="255.255.255.192"
gateway="151.39.235.193"
hostname="vx1.sysman.iol.it"

extra="3"

But domU does not start:

xen:~# xm create vx1.cfg -c
Using config file "/etc/xen/vx1.cfg".
Error: Device 2049 (vbd) could not be connected. Backend device not found.

In /var/log/xen-hotplug.log I've found:

interface vif1.0 does not exist!
xenstore-read: couldn't read path backend/vbd/1/2049/node
xenstore-read: couldn't read path backend/vbd/1/2050/node

xenstore-read: couldn't read path backend/vbd/4/2049/node
xenstore-read: couldn't read path backend/vbd/4/2050/node

And in /var/log/xend.log I got:

Maybe can something be wrong in /etc/xen/xend-config.sxp ? Now is
uncommented only:
(network-script network-bridge)
(network-script network-dummy)
(vif-script vif-bridge)



Thanks
Stefano
